The MIT515, MIT525, MIT1025, and MIT1525 insulation resistance testers are designed to test high-voltage power cables and buses, large motor/generator windings, as well as line and substation transformers for insulation resistance. Courtesy: MeggerA new series of insulation resistance testers is capable of safely testing both high- and low-voltage equipment. The MIT515, MIT525, MIT1025 and MIT1525 feature testing techniques that provide valuable diagnostic information to the user. Each of the instruments easily can test high-voltage power cables and buses, large motor/generator windings, as well as line and substation transformers for insulation resistance. Rated at 5 kV and 10 kV, the MIT515, MIT525 and MIT1025 are engineered to ensure the highest precision possible. The MIT525, MIT1025 and MIT1525 perform spot tests, step voltage tests, dielectric discharge tests, ramp tests and dielectric absorption tests for QA testing in manufacturing processes, diagnostic tests to isolate faulty components for repair, as well as routine preventative/predictive maintenance. Each unit has a noise filter that can reject up to 3 mA on the 5 kV and 10 kV models and 6 mA
